What is the summation notation for the geometric series 5 + 10 + 20 + 40 + 80?

Gekata [30.6K]

Anyhow, the common ratio is 2, and the first term is 5 and since there are 5 terms, n = 5,

$\bf \qquad \qquad \textit{sum of a finite geometric sequence}
\\\\
S_n=\sum\limits_{i=1}^{n}\ a_1\cdot r^{i-1}\implies S_n=a_1\left( \cfrac{1-r^n}{1-r} \right)\quad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
r=\textit{common ratio}\\
----------\\
a_1=5\\
n=5\\
r=2
\end{cases}
\\\\\\
\sum\limits_{i=1}^{5}~5\cdot 2^{i-1}$

Write each decimal as a percent and a fraction -0.04

Annette [7]

Answer:

-4% -1/25

Step-by-step explanation:

To convert a decimal to a percentage, multiply it by 100.

-0.04 * 100 = -4

To convert a decimal to a fraction, put the decimal as a fraction over 1 and multiply until the numerator (top number) is a whole number and then simplify.

$\frac{-0.04}{1}$ x $\frac{100}{100}$ = $\frac{-4}{100}$

-4/100 simplified = -1/25 (because 4 goes into 100 25 times)
